What This Standard Means
What Students Need to Do
- Students identify the prefix and base word in an unfamiliar word. They read each part, blend the parts, and check the pronunciation in the sentence.
What Mastery Looks Like
- A student can mark the prefix in words such as preview, misplace, and nonfiction, then read each word accurately. The student keeps the base word recognizable and checks the pronunciation in context.
Common Misconceptions
- Students may treat any opening letters as a prefix, splitting reach as re + ach. They may also omit or mispronounce the prefix while reading the base correctly.
How to Assess It
- Exit ticket: Students underline the prefix in preview, misread, and unsafe, then read each word aloud and name its base word.

Ways to Teach It
Give students prefix and base-word cards, such as un + kind and re + play, to combine, divide, and read aloud.
Write, “How did the prefix help you read misbehave?” Students mark the word parts and explain their steps to a partner.
Play Prefix Match, where students pair prefix cards with base words and keep each pair after reading the completed word accurately.
Collect prefixed words from signs, menus, or app screens, then create a class list with marked prefixes and practiced pronunciations.
